When Elon Musk stunned the automotive world with the reveal of the Tesla Roadster, speed junkies everywhere reeled at the potential promised by the new sedan.

Now, not even a week after the Musk rattled off the ridiculous specs purportedly achieved by his prototype, another electric car startup has burst onto the scene with similarly outsized claims and plans to take the high-speed performance off-road.

Taipei-based powertrain maker XING Mobility just announced that it’s well along in the testing process for its new supercar prototype, the Miss R. The all-electric, rally-inspired beast will have both on-road and off-road capabilities and use a new modular, immersion-cooled battery system, which the company developed internally with chemical maker 3M’s technologies.

The Miss R prototype will challenge the Tesla Roadster for the title of the world’s fastest car once both the speedsters actually hit the road. XING claims its rally-capable monster will be depend on four independent 350V motors to accelerate from 0 to 100 km/h in 1.8 seconds, 0 to 200 km/h in 5.1 seconds, and max out at a top speed of over 270 km/h.

Tesla’s specs for the Roadster have all been provided in the American standard of miles per hour — 0 to 60 mph in 1.9 seconds, 0 to 100 mph in 4.2 seconds, top speed of over 250 mph — but even so, it appears that on paper the Miss R could become the new king of automotive acceleration, since 100 km/h equals roughly 62 mph.

XING has already tested out the powertrain and battery system in an exposed drivetrain prototype. The company released some footage in a teaser video, which you can check out below:
